| A | B |
|---|
| How is sound produced? | sound is produced by a vibration of molecules |
| How does sound travel? | it starts with a vibration at the sorce and travels through a medium |
| What must sound waves travel through? | molecules of some type of medium |
| Name three examples of solids. | Metal- traintrack, folder or paper, wood or a desk |
| Name an example of a liquid. | Water- ocean, river, lake, creek |
| Name an example of a gas. | Air- oxygen molecules |
| What instrument do scientists use to observe sound waves? | They use a oscilliscope |
| What kind of wave does sound travel in? | A compressional wave |
| What happens in a compressional wave? | The molecules are being pressed together and move back and forth with the wave |
| Where are molecules tightly packed? | In a compression |
| Where are molecules loosley packed? | In a rarefaction |
| What can happen when sound travels through matter? | It can get transmitted, asorbed, or get refelcted |
| What does reflected mean | It means waves bounce off an object or goes back |
| What does asorbed mean? | It means the waves are trapped or broken up by an object |
| What does transmitted mean? | It means energy waves pass through an object |
| What is most likley going to happen when sound travels through an object? | The waves are most likley to reflect the object |
